Low light in the speedometer can be caused by dirt / dust build-up in the metal housing that contains the speedometer mechanism. It's white on the inside to reflect the light. If you take it apart and clean it out, you will be surprised how well these old style instruments are lit. They are not unsafe if they are kept in good working order.
